Why is car engine bucking with warning light on?
I took my car to change the oil and after that the check engine light came on and the car bucked at low speed. I finally found that the large tube that went from the air filter to the throdle body had a large crack in it and was causing the problem. I did a code scan on my 1994 Lexus es300 and it showed that a O2 sensor was bad but the new hosefixed the problem. if the hose is ok Iwould check to see if there are any vacuum laks in that area.

How do you turn of the check engine light in a 92 Ford Escort?
You must diagnose and fix the problem. A 1992 is equipped with OBD1 diagnostics, so the light wouldn't be on if the computer wasn't seeing a problem.
It's most likely that your alternator is bad. Most auto parts stores will check them for free, or you can have your local garage test it. A bad ground probably is not the source of your problem, since the brightness varies with engine RPM. Add a ground strap between the engine and the firewall ans go to bare metal. Most problems like yours are due to bad grounds. Older vehicles had good grounds but sometimes people remove them because they don't think they are important and also as the car gets older, these grounds corrode. check your battery and your charging system. a weak battery/alternator can cause those symptoms.
I just got my f-150 fixed with that same problem. I replaced the spark plugs and spark plug wires. The blinking check engine light is caused by excess gas coating the catalytic converter sensor. If left unfixed this will cause permanent damage to the catalytic converter.
How do you reset the check engine light on a 1998 Jeep Wrangler Sport?
You reset it with an OBD2 scan tool after repairing the problem detected by the computer. Otherwise it will just come back on.
The check engine light is telling you that the computer has information that you should read. You can find out what the engine fault code is by turning the ignition key to the run position (don't engage the starter, you are not trying to start the car) then back to the off position 3 times within 10 seconds. On the 3rd cycle, leave the key in the on position and look at the odometer. If it is digital, the accumulated miles will be replaced with various code numbers that flash by. Write these numbers down, as they are the fault codes that you are looking for. No need to purchase or rent a code reader. All dodge products have the code reader built into the dash. If your odometer is not digital, then the check engine light will start to flash. Count the flashes and write down the corresponding number. Remember that each code requires three digits. Example: a code 340 would look like 3 flashes, pause, 4 flashes,pause then the light goes out. These number codes can now be compared to a code list of faults for you vehicle. Check around the internet for the engine fault codes for your vehicle, then you will find out what your on board computer is finding as the problem. Hope this helps Gummibear

What does it mean if the engine light comes on intermittently on astra?
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
